仔细阅读sql我们发现该sql有一个重复出现的查询体
(SELECT T.ORG_NO, T.TG_ID, A.AUTH_USER_NO
FROM K_ID_G_TG T,
K_ID_GR_TG_RELA R,
K_ID_GRID_BUSS B,
K_ID_STAFF A
WHERE R.DATA_OPER_TYPE != 'D'
AND R.TG_ID = T.TG_ID
AND B.GR_ID = R.GR_ID
AND B.DATA_OPER_TYPE != 'D'
AND A.DATA_OPER_TYPE != 'D'
AND A.STAFF_NO <> '无'
AND A.STAFF_NO IS NOT NULL
AND B.BUSS_NO = A.STAFF_NO
AND A.AUTH_USER_NO IS NOT NULL
AND A.AUTH_USER_NO != '无') F1
共出现了5次。
对于这类重复出现的查询体，我们通常用with进行改写
从执行计划看到访问G_TG表，才发现K_ID_G_TG表对应的是一个视图。
create or replace view k_id_g_tg as
select "TG_ID","ORG_NO","TG_NO","TG_NAME","TG_CAP","INST_ADDR","CHG_DATE","PUB_PRIV_FLAG","RUN_STATUS_CODE","REMARKS","AREA_TYPE","PF","IS_EXCE_TG","RATE_TIME","DWDM","DATA_TIME"
from (select tg_id,
(select p_dim_id
from k_ic_dim_value
where dim_value = a.org_no
and dim_code = 'dept') org_no,
tg_no,
tg_name,
tg_cap,
inst_addr,
chg_date,
pub_priv_flag,
run_status_code,
remark remarks,
area_type,
pf,
(select is_exce_tg from k_id_g_tg_jp where tg_id=a.tg_id and rownum=1) is_exce_tg、,
(select rate_time from k_id_g_tg_jp where tg_id=a.tg_id and rownum=1) rate_time,
org_no dwdm,
sysdate data_time
from g_tg a
where a.pub_priv_flag = '01'
and run_status_code = '01')
where org_no is not null;
查看视图，视图中出现的org_no、is_exce_tg、rate_time字段，我们根本用不上,查询基表足矣。
所以with可以改写如下：
with F1 as
(
SELECT T.ORG_NO, T.TG_ID, A.AUTH_USER_NO

K_ID_GR_TG_RELA R,
K_ID_GRID_BUSS B,

AND A.AUTH_USER_NO != '无'
AND A.AUTH_USER_NO = 'P6xxxxxxx1'

再次执行查询，还是查不动。
我们分别对union all上下关联的sql进行分析
SELECT FF.GDS_NO,
F1.AUTH_USER_NO,
COUNT(DISTINCT FF.TG_ID) COUNT,
'PD0009' IDX_CODE
FROM (SELECT F.GDS_NO, F.TG_ID

TO_CHAR(SYSDATE, 'yyyymm')
GROUP BY F.GDS_NO, F.TG_ID
HAVING COUNT(DISTINCT F.MSG_ID) >= 2) FF,
F1
WHERE F1.TG_ID = FF.TG_ID
AND F1.ORG_NO = FF.GDS_NO
GROUP BY F1.AUTH_USER_NO, FF.GDS_NO
该步骤执行慢。
从执行计划中看出，走的是TAG_NO的索引。
通过dba_tab_col_statistics发现TAG_NO distinct值为2。
全表数据量约为500w。
分析其他过滤条件MAKE_TIME列，数据比较倾斜，201910月数据为200w，其他月份数据量偏少，最高只有10w左右。
所以删除了原先TAG_NO列索引 drop index cpss.IDX_TAG_NO1;
创建函数索引
create index cpss.idx_MAKE_TIME on cpss.K_AMR_GBTD_FLOW(substr(replace(MAKE_TIME, '-', ''), 1, 6),TAG_NO);
执行计划如下：

3秒内出结果，业务正常。
该sql还存在优化空间，K_AMR_LBTZ_FLOW表也可以加上同样的函数索引。
create index cpss.idx_MAKE_TIME on cpss.K_AMR_LBTZ_FLOW(substr(replace(FIRST_TIME, '-', ''), 1, 6),TAG_NO);
将K_AMR_GBTD_FLOW表重复的查询同样用with改写
针对SELECT FF.GDS_NO,
F1.AUTH_USER_NO,
COUNT(DISTINCT FF.TG_ID) COUNT,
'PD0009' IDX_CODE
FROM (SELECT F.GDS_NO, F.TG_ID
FROM K_AMR_GBTD_FLOW F
WHERE F.TG_ID IS NOT NULL
AND F.GDS_NO IS NOT NULL
AND F.TAG_NO = 'TagPBGZTD'
AND SUBSTR(REPLACE(MAKE_TIME, '-', ''), 1, 6) =
TO_CHAR(SYSDATE, 'yyyymm')
GROUP BY F.GDS_NO, F.TG_ID
HAVING COUNT(DISTINCT F.MSG_ID) >= 2) FF,
F1
WHERE F1.TG_ID = FF.TG_ID
AND F1.ORG_NO = FF.GDS_NO
GROUP BY F1.AUTH_USER_NO, FF.GDS_NO
这条sql语句，我们可以在索引上加上更多的列，减少回表操作(但是维护索引中的各个字段，将会增加其他dml操作的时间)
create index cpss.idx_MAKE_TIME on cpss.K_AMR_GBTD_FLOW(substr(replace(MAKE_TIME, '-', ''), 1, 6),TAG_NO,GDS_NO,TG_ID,MSG_ID);
